A 21-dBm $I/Q$ Digital Transmitter Using Stacked Output Stage in 28-nm Bulk CMOS Technology


This paper proposes the use of a high-power stacked output stage for a current-based in-phase/quadrature (<inline-formula> <tex-math notation="LaTeX">$I/Q$ </tex-math></inline-formula>) direct digital to RF modulator (DDRM) in bulk CMOS. The main nonlinearities associated with implementing the stacked transistor on top of the <inline-formula> <tex-math… (More)
